I got one this morning, I was on another call. They did not leave a message.

Voice message indicates that they are experts in home security system

This [***] call me and I am on the National DO NOT CALL list.  They say they are giving away a free home security system.  I hit one to talk to someone and when I said I was upset with the call they hung up.  I called back and got the "This number does not exist" message.

I will report this to the nation do not call people.

Received call from this number 12/6 at 6:28 p.m.  Said they were home security experts and wanted to give me a free system. I am on the DO NOT CALL LIST which doesn't seem to be working anymore. I blocked the numbers they call from but my phone service only allows for 12 blocked numbers and mine is full with these calls so I can't block anymore. I've turned them into the FTC and heard nothing.  Where are our legislatures that could go after these people.  They like to send through bills, then write one for this problem.  I'm sick of telemarketers !!!!!

I get calls from this number 3 or 4 times a day, both cell and land line. Automated message starts out "Do Not Hang Up this is not a sales call." goes on about a "free" secuity system.   Right!    I don't want what ever it is that they are hawking, doubt if it is free. Hanging up didn't work then I tried to press  #2 to register that I do not calls about this, but am still getting calls, then I tried press #1 to talk to someone and got a full voice mail?  No one to talk to.
I am registered on the National Do Not Call List for both phones, but it made no difference. How can I get these calls to stop?
